Change history of GDPDM from version
April 25, 2005 to version April 29, 2005.
---------------------------------------------

- Moved reference to div_scoring_tech_type
  to table div_allele_assay instead of
  div_aa_annotation.

- Corrected div_taxa_family to reflect levels
  for plant instead of animals.

- Added field common_name to the
  div_taxonomy table.

- Changed all primary and foreign keys
  to be unsigned integers.   Effectively
  doubling the range of values as keys
  generally are not negative.

- Changed data type of div_trait_uom.to_accession
  and div_treatment_uom.eo_accession to varchar
  instead of int.  Necessary for integration
  with Gramene.

- For consistency, changed the following
  field names to "comments":
  div_passport.remarks
  div_stock.remarks
  div_synonym.remarks
  div_generation.remarks
  div_obs_unit.summary
